PIPE-WRENCH.

v SPECIFICATION forming part of Letters Patent No. 401,926, dated April23, 1889.

Application filed December 27, 1888. fierial No'. 294,811. (No model.)

To all whom it may concern.-

. Be it known that I, LEwIs J. BERGENDAHL, a citizen of the UnitedStates of America, residing at Pendleton, in the county of Umatilla andState of Oregon, have invented certain' new and useful Improvements inPipe- Wrenches; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled inthe art to which it appertains to make and use thesame, reference being had to the accompanyin g drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

My invention relates to new and useful improvements in pipe-wrenches;and it consists in the novel construction and arrangement or combinationof the parts thereof, as will be more fully hereinafter described andclaimed.

The object of my invention is to provide a pipe-wrench which will notslip from the pipe or around the same after being attached thereto, theparts thereof being of simple and effective construction, strong anddurable, and inexpensive in manufacture. I attain this object by theconstruction illustrated in the accompanying drawings, wherein likeletters of reference indicate similar parts in the several views, and inwhich Figure 1 is a perspective view of my improved wrench. Fig. 2 is aside elevation thereof. Fig. 3 is a transverse vertical section on theline 00 a: of Fig. 2.

A indicates therein or handle of the wrench, whose front end isprovidedwith an enlarged integral formation comprising front V-shapedserrated grips, a a, in rear of which ,on two sides of the handle, lugsa are arranged and provided with an intersecting space, a The said gripsa are also separated by an intersecting space, a for a purposehereinafter explained.

By means of a rivet, a, the end link of a chain, B, is secured in theopening or space a between one pair of the lugs a, the space between theother pair of lugs and the space I between the grips a being open andfree of obstruction for the passage of the chain B therethrough.

Directly in rear of one pair of lugs 01, a rod, 0, is centrally andvertically mounted in the handle A,-having a hooked end, 0, andshoulders 0 formed therewith, which bear against the two opposite sidesof the handle to prevent said rod from becoming displaced from thehandle and to allow it to be revolved.

In operation the chain B is thrown around the pipe to be turned orwrenched and passed through the lugs 11 in front of the hooked rod 0.The serrated V-shaped grips are caused to closely impinge against thepipe, and a link of the chain B is thrown over the hooked end 0 of therod 0. The wrench as thus arranged will be ready for work, and may beturned in either one of two directions, or, if desired, may be reversedand the hooked end 0 of rod 0 be onthe top or bottom. The V- shapedconstruction of the grips a readily permit and are especially adaptedfor this reverse op erafiiveness. n

The special function of the revoluble hooked rod 0 lies in itsadaptation to engage the links of the chain B at any angle, therebyavoiding the necessity of a precise adjustment of said links in order tothrow the same over the hooked rod.

Having thus described my invention, what I claim as new, and desire tosecure by Lettei s Patent, is

In a pipe-wrench, a rein or handle having an enlarged integral formationat one end, comprising V-shaped grips with an intersecting space, andpairs of lugs with openings between them arranged in rear of said grips,a chain connected to and mounted between one pair of said lugs, and arevoluble hooked rod mounted in said handle in rear of the other pair oflugs and adapted to be engaged by the links of the said chain,substantially as described.

In testimony whereof I alfix my signature in presence of two witnesses.
